Ingredients

Preparation

Spray baking sheet with nonstick spray. Stir sugar and water in heavy small saucepan over medium-low heat until sugar dissolves. Increase heat; boil until deep amber color, occasionally brushing down sides of pan with wet pastry brush and swirling pan, about 12 minutes.

Stir nuts into caramel and immediately pour onto prepared sheet. Working quickly and carefully (caramel is very hot and hardens fast), press tip of small knife into edges of caramel and gently stretch in all directions to form very thin sheet, approximately 12 by 10 inches. Cool brittle completely.

Break brittle into irregular pieces. DO AHEAD Can be prepared 3 days ahead. Store airtight at room temperature.
